PHP如果未在數組中找到未設置的父項

如果我沒有在我的孩子中找到我的針，但由於某種原因，我無法讓此工作，無論我嘗試了多少種不同的方式它，有人可能指向我在正確的方向嗎？這是在一個底層深度約爲4的多維數組中拋出的。下面是代碼和數組的一部分可能的樣子。在這種情況下，只有Array [3]應該保留，Array的[1-2]應該被移除。PHP如果未在數組中找到未設置的父項

array (

這是我嘗試使用的最後一個代碼沒有成功的樣本，如果你替換unset（$ k）;返回錯誤;它將返回其二級陣列針出現英寸

// array_search with recursive searching, optional partial matches and optional search by key 
    function array_find_r($needle, &$haystack, $partial_matches = false, $search_keys = false) { 
     if(!is_array($haystack)) return false; 
     foreach($haystack as $key=>&$value) { 
      $what = ($search_keys) ? $key : $value; 
      if($needle===$what) return $key; 
      else if($partial_matches && @strpos($what, $needle)!==false) return $key; 
      else if(is_array($value) && array_find_r($needle, $value, $partial_matches, $search_keys)!==false) return $key; 
     } 
     unset($k); 
    } 

$tty = array(); 
foreach($datas as &$k) { 
    $tty[] = array_find_r('Jedi', &$k, true, false); 
} 

$tty=array_filter($tty); rsort($tty); 


echo '<pre>'; var_export($datas); echo '</pre>';

爲什麼不把你確實需要進入一個新的數組，並取消了整個舊陣列中的數據？
